Civil Procedure QUESTION #3688

A plaintiff (State A) sues Defendant 1 (State B) and Defendant 2 (State B) for $\text{\$100,000}$ in federal court. Defendant 1 files a cross-claim against Defendant 2 for $\text{\$10,000}$ arising out of the same car accident. Defendant 2 moves to dismiss the cross-claim for lack of subject-matter jurisdiction because it is under $\text{\$75,000}$. How should the court rule?

Grant the motion, because the cross-claim does not meet the amount in controversy.
Grant the motion, because there is no diversity between Defendant 1 and Defendant 2.
Deny the motion, because the court has supplemental jurisdiction over the cross-claim.✔️
Deny the motion, because cross-claims are always federal questions.

Correct Answer Logic:

Under 28 U.S.C. $\S 1367$, the court has supplemental jurisdiction over cross-claims (Rule 13(g)) that arise from the same transaction or occurrence as the original claim, regardless of the amount or diversity between the co-defendants.

Mathematics QUESTION #1320

Question 2104

If two vectors $\vec{a}$ and $\vec{b}$ satisfy $\vec{a}\times\vec{b}=\vec{0}$ and $\vec{a}\neq\vec{0}$, $\vec{b}\neq\vec{0}$, then:

They are perpendicular
They are parallel✔️
Their magnitudes are equal
Their dot product is zero

Correct Answer Logic:

The cross product $\vec{a}\times\vec{b}=|\vec{a}||\vec{b}|\sin\theta\,\hat{n}$. If $\vec{a}\times\vec{b}=\vec{0}$ and neither vector is zero, then $\sin\theta=0\Rightarrow\theta=0$ or $\pi$, meaning the vectors are parallel (or anti-parallel).

Physics QUESTION #1187

Question 2105

The relation between half-life and mean life are:

Inversely proportional
Directly proportional✔️
Equal
Half

Correct Answer Logic:

Half-life $t_{1/2}$ and mean life $\tau$ are related by: $t_{1/2} = \tau \ln 2 = 0.693\,\tau$. Since $t_{1/2} = 0.693\,\tau$, they are directly proportional to each other (one is always a fixed constant times the other). The half-life is always shorter than the mean life by a factor of $\ln 2$.

Question 2110

In a balanced three-phase star-connected system, what is the phase relationship between the line voltage $V_L$ and its corresponding phase voltage $V_{ph}$?

$V_L$ leads $V_{ph}$ by $30^\circ$✔️
$V_L$ lags $V_{ph}$ by $30^\circ$
$V_L$ and $V_{ph}$ are in phase
$V_L$ leads $V_{ph}$ by $120^\circ$

Correct Answer Logic:

In a star (Wye) connection, the line voltage is $\sqrt{3}$ times the phase voltage and leads the phase voltage by $30^\circ$.

Question 2112

The lumped capacitance (lumped system) method for transient heat transfer is valid when the Biot number satisfies:

$Bi > 10$
$Bi \geq 1$
$Bi \leq 0.1$✔️
$Bi = 1$ exactly

Correct Answer Logic:

The lumped capacitance method is valid when $Bi=hL_c/k\leq0.1$. The temperature history is: $\frac{T-T_\infty}{T_i-T_\infty}=e^{-t/\tau}$ where $\tau=\rho c V/(hA_s)$ is the time constant.

Physics QUESTION #1029

Question 2116

In an oscillating spring-mass system, sand leaks slowly out of the box vertically as it oscillates. Which schematic correctly shows changes in average frequency $\omega(t)$ and average amplitude $A(t)$ with time?

Frequency increases (curve up), amplitude increases (curve up)✔️
Frequency decreases (curve down), amplitude decreases (curve down)
Frequency increases (curve up), amplitude stays constant (flat)
Frequency increases (curve up), amplitude decreases (curve down)

Correct Answer Logic:

As sand leaks out, mass decreases. $\omega = \sqrt{k/m}$: as $m$ decreases, $\omega$ increases. Amplitude: since sand leaks vertically (no horizontal impulse), energy is not added but mass decreases — the amplitude increases as $A = v_{max}/\omega$ and the system conserves momentum. Frequency increases and amplitude increases gradually.

Question 2118

The reactivity order of alkyl halides for a particular alkyl group is:

$\text{F} > \text{Cl} > \text{Br} > \text{I}$
$\text{I} > \text{Br} > \text{Cl} > \text{F}$✔️
$\text{Cl} > \text{Br} > \text{F} > \text{I}$
$\text{Br} > \text{I} > \text{Cl} > \text{F}$

Correct Answer Logic:

Reactivity of alkyl halides in nucleophilic substitution follows bond strength (C–X bond): C–I is weakest so iodide is most reactive. Order: $\text{I} > \text{Br} > \text{Cl} > \text{F}$.
